Objectives To investigate the effect of PDCA cycle management on effect of pressure steam sterilizer in disinfectantion supply center.

Methods Samples of pressure sterilizers were sampled for 6 months before and after the implementation of the PDCA cycle management program, the number of testing samples per month was 40, 60 samples of each pressure steam sterilizer were extracted before and after the implementation, and the effect of sterilization was detected; 100 clinical satisfaction questionnaires were investigated at 6 months before and after the implementation.

Results After the implementation of PDCA, the qualified rate of sterilizing samples was 98.75%, which was significantly higher than that before the implementation 91.67% (P < 0.05). After the implementation of PDCA, the qualified rate of No. pressure sterilizer was higher than that before implementation (P < 0.05). After the implementation of PDCA, the measured temperature unqualified rate of the pressure steam sterilizer was 0.83%, which was significantly lower than that before the implementation 9.17% (P < 0.05). After the implementation of PDCA, the satisfaction of clinical medical staff to the disinfection supply center was 98%, which was significantly higher than that before the implementation of the 90.00% (P < 0.05).

Conclusions The implementation of PDCA cycle management for quality continuous improvement can effectively improve the effect of pressure sterilizer in the sterilization supply center, and strongly support the hospital sense control.
